Address and Routing Parameter Area
Securebit Tools Network ARPA (RDNS)


This tool will generate an PTR record for DNS Servers like BIND from an IPv4 or IPv6 address using the nibble format. Nibble format is a dot-separated reversal of all the (hex) digits in the expanded address and allows greatly improved delegation of Reverse DNS at the expense of human usability of zone files - hence this tool.
